Cold-Climate Heat Pumps Explained
Posted On: February 2, 2026
If you’ve heard that heat pumps don’t work in cold weather, you’re not alone.
That used to be true.
Today’s cold-climate heat pumps are designed specifically to handle freezing temperatures—and they’re becoming one of the most efficient heating options for homes in cold regions.
At Twintech Heating & Cooling, we install and sell modern cold-climate heat pumps, and homeowners are often surprised by how well they perform—even during harsh winters.
Let’s break it down.
What Is a Cold-Climate Heat Pump?
A cold-climate heat pump is a high-efficiency heating and cooling system engineered to operate in temperatures well below freezing, depending on the model.
Instead of generating heat by burning fuel, a heat pump:
Pulls heat from the outside air (yes, even cold air contains heat)
Compresses and transfers that heat indoors
Reverses in summer to provide air conditioning
Cold-climate models use:
Advanced inverter-driven compressors
Enhanced refrigerants
Improved defrost cycles to maintain consistent heat in winter.
Do Heat Pumps Really Work in Cold Weather?
Yes—when you install the right system for the climate.
Older heat pumps struggled below certain temperatures.
Modern cold-climate heat pumps are specifically designed for winter performance and can:
Maintain indoor comfort in sub-zero temperatures
Deliver steady heat without temperature swings
Operate far more efficiently than electric resistance heat
In many homes, they can replace a traditional furnace—or work alongside one in a dual-fuel setup.
Heat Pump vs Furnace in Cold Climates
Here’s how cold-climate heat pumps compare to traditional systems: Heat Pumps
Extremely energy efficient
Lower operating costs
Provide both heating and cooling
Reduce reliance on fossil fuels Furnaces
Very strong heat output in extreme cold
Often paired with heat pumps for backup
Higher fuel costs over time
Many homeowners choose a dual-fuel system, where the heat pump handles most heating, and a furnace kicks in only during extreme cold.
What About Ice and Defrost Cycles?
You may notice frost on the outdoor unit in winter—that’s normal.
Cold-climate heat pumps use automatic defrost cycles to:
Melt ice buildup safely
Maintain heating performance
Prevent damage to the system
A properly installed heat pump will manage this seamlessly without affecting indoor comfort.
Are Cold-Climate Heat Pumps Worth It?
For many homeowners, absolutely.
Benefits include:
Lower monthly energy bills
Fewer mechanical parts than combustion systems
Quiet operation
Long system lifespan
Possible rebates and incentives
The key is professional sizing and installation.
An undersized or improperly installed system won’t perform as intended.
Is a Cold-Climate Heat Pump Right for Your Home?
Cold-climate heat pumps are ideal for:
Homes with moderate to good insulation
Homeowners looking to reduce energy costs
Properties replacing older furnaces or AC units
New installations or system upgrades
At Twintech Heating & Cooling, we evaluate your home, climate needs, and comfort goals to recommend the right heat pump system—not a one-size-fits-all solution.
Professional Heat Pump Installation Matters
Performance depends heavily on:
Correct system sizing
Proper refrigerant charge
Smart thermostat integration
Quality installation
That’s why working with an experienced HVAC contractor is critical.

The sales process was friendly, informative, and very consultative. They worked hard to earn our business by taking a careful look around our home to assess our needs, providing a lot of information about the product, and answering all our questions and finding the right solution for our home at a competitive price. They prepared us very well for what to expect on installation day, and the installation went very smoothly - no surprises, all very professional! They gave us a call after installation to ensure we were happy with the work. We're very happy that we chose to work with TwinTech to get our new furnace.

When our old oil furnace finally broke down we decided it was time to finally convert to natural gas and finally install central air conditioning at the same time. Knowing it was going to be a significant investment for us, we wanted to make the right choice. Twintech came highly recommended by a friend and we were not disappointed. From the first contact with the salesperson, until the final touches on the installation, we were so pleased with their service. Everyone from the company was so friendly, efficient and a pleasure to deal with. Best of all, the cost was very competitive. We would certainly recommend Twintech to anyone requiring HVAC work in their home.

Mitch from Twintech came out for our annual furnace inspection. We found him to be friendly, conscientious & he left the work area clean. We were also very impressed with the thoroughness of the job he did. This is the 2nd job weve had Twintech do for us & have been very happy with the results for each. We highly recommend this company. Thank you, Mitch, Dave & Greg.

During the hottest week in the summer our old A/C decided to call it quits. I called Twintech Heating & Cooling after receiving a referral from a family member; came highly rated for being an honest, family-run business, who appreciates their customers. Dave was able to accommodate my hectic schedule and book a late evening appointment to walk through the specifics. Greg and Mitch arrived exactly on time a few days later, were very polite and friendly, and within a couple of hours had a new unit up and running. I also received a follow-up call to ensure we were happy with the Amana.
Jan 10, 2020
They were on time and very professional. I'm so glad I decided to go with Twintech, thanks!
